Recommendations for powders, 742 Carbine .30-06

[menotomyhunter]

I have a Model 742 Carbine in .30-06. This rifle has been thoroughly tuned by someone who knows what they are doing! It functions flawlessly with 150 grain Federal ammo. I want to try reloads for it using 150 and 165 grain bullets. I am looking for powder recommendations as its barrel length is 18.5 inches. Recommendations welcome!

I'ver reloaded 3006 for a standard barrel 742 for decades. My favorite powders are IMR4350, 4041, and Rel 15. For a carbine barrel these may give some flash but they work well in the 742 with 150gr. I use moderate loads and do not try for speed records.
